Comparative Study of Multiple High-Signal-Intensity Spots on 3D and 2D Magnetic Resonance Sialography for Patients with Sjögren’s Syndrome

Figure 2

A case of the usefulness in determining the imaging side for unilateral sagittal 3D MR-S with T1- and T2-weighted images. T1-weighted image (a) and fat-suppressed T2-weighted image (b) showed HD of the parotid gland with left predominance. This case had no MHS in bilateral 2D MR-S (c, d). We determined the imaging side (right or left) for unilateral sagittal 3D MR-S by evaluating the HD on T1- and T2-weighted images (b, c). Unilateral left 3D MR-S (e) clearly depicted MHS. MR-S: magnetic resonance sialography; HD: heterogeneous distribution; MHS: multiple high-signal-intensity spots.
